M5 x 12mm Thin Knurled Thumb Screw (DIN 653) | A1 Stainless Steel

Frequently selected for machine panels and production jigs, this M5 x 12mm low-profile thumb screw delivers hand tightening in a compact DIN 653 form. The textured head edge supports positive grip and the 12mm thread offers general-purpose engagement for covers, brackets and compact assemblies without introducing a separate knob or handle.

What Are Thin Knurled Thumb Screws?

A low-profile knurled thumb screw combines a standard metric thread with a broad hand-operated head. The reduced head thickness keeps the fixing compact while the knurled perimeter provides the friction needed for controlled manual tightening.

Common Applications

  • Workshop Fixtures: Fastens adjustable parts that operators need to release regularly.
  • Test Equipment: Provides controlled hand fastening for fixtures used during repeated trials.
  • Machine Panels: Secures service panels that are removed during inspection or maintenance.
  • Production Jigs: Allows stops, guides and fixture parts to be repositioned without tools.
